When the 18-year-old told the kind-hearted police officer that his graduation was just days away and he didn't know what to do, Ellison told him he would be there for him.

Mr Ellison told Buzzfeed News that he told Kazzie he wouldn't miss the milestone for the world.

He explained: "I said, 'You are going to walk!'

"Your mom and dad will have front-row seats looking down from heaven, and I'll stand in their place. I've got your back."

The veteran police officer said the accident and Kazzie struck a chord with him, especially as his own daughter had just graduated recently.

He said being there for Kazzie was "the right thing to do."

He added: "I had to be the bearer of bad news for him, and I felt that was just the right thing to do."

And this Saturday when Kazzie's name was called to receive his diploma, the entire stadium at the Little Cypress-Mauriceville High School erupted and gave the teen a 40-second standing ovation.

True to his word, Ellison was standing at the other side of the stage dressed in full uniform, ready to congratulate Kazzie with a massive hug.

Kazzie's brother Blake Henning posted a video of the incredible moment to Facebook and said he knew his mum and dad were proud of him.

Blake said: "This was such a special moment. Thank you class of 2015 for making this such a memorable occasion for our family.

"So proud of you @kazz418 I love you so much. Throughout all of this you have been so strong and we are so proud of you.

"Thank you for being such a great brother. I am so excited to see what the future holds for you. I know mom and bubba are so proud of you."

And Kazzie told Buzzfeed News that he wasn't able to describe how much the incredible moment meant to him.

The youngster revealed: "Seeing Officer Ellison there to congratulate me meant the world to me.

"It was so nice to see that he actually showed a genuine care for me and my family's situation instead of us just being another 'case'."

And he added that the "never-ending" love and support his family has received from their community since their parents' tragic deaths has been astounding.

Kazzie said: "I'll never be able to thank enough some very few people that stayed with me through the days and as well as everyone that helped me in any way at all and all the people praying for me and my family."

But Kazzie's story isn't the only one that's melted our hearts: This Aussie student adopted his pregnant, homeless cousin to give her a chance 'at a better life'.

And strangers raised thousands for a man who couldn't afford a car and faced a 21-mile daily trek to work.
